rvwilyszsz 2 The shafts llof the. upper rolls 15, 15, 3

l5". and 15, are mounted in housings 16, which rest upon the oppositeupper longitudinal liars 2* of the frame.

slots 2 are formed in the bars Longitudinal to receive Q the dependingheads ot bolts 17, which pass lower rolls, means for ad usting the lowerthrough the housings 1t and are secured at the top hy nuts tts'. It isthus apparent that by loosening the nuts 13 of any pair at housings It).said housings and their roll-shaft and roll may he moved longitudinallyof the apparatus, and independently of any other roll. In order thattlt'll pair of housings 16 may he moved together, it is preferred toconnect them together. as by webs 19.

The upper roll-shatts and rolls may also each be made verticallyadjustahle. in any well known or suitable way. The shafts are hereinshown as journaled in blocks 20, carried by screws ll 'rotatahly mountedin the housings 1(3 aml provided with hand-wheels 22. In order thatthevertieal adjustment of hoth ends of each roll-shaft may he evenlyaccomplished by turning either hand-wheel, the shafts of each pair ofscrews 20 are provided with sprockets 23 connected by chains 2 t.

It is obvious that the numher of rolls used maybe varied, as well asthat the upper rolls might be driven, and many other changes may he madeby those skilled in the art without departure from the spirit of theinvention. Also the apparatus may housed for bending, as well as forstraightenin", pieces of metal.

By making the rolls adjustahle hoth vertically and longitudinally of theapparatus, it is obvious that pieces of metal of widely varyingthicknesses may he effectively straightened, and the apparatus is thusgiven a much greater range in working capacity than any with which I amaciplainted. Also by the independent adjustment of individual rolls, theapparatus is rendered very flexible, and the relative positions of anyof the rolls may be qnicldy altered to suit varying eonditions.

I claim as my invention:

1. In an apparatus for straightening metallic articles. the. combinationwith a series of lower rolls, of a series of upper rolls,

BEST AVAILABLE COP? ently of each of the other rolls of said series,

and means for adjusting each of the rolls of one series in a horizontaldirection independently of each of the other rolls of saidlast-mentioned series.

3. In an apparatus for straightening metallic articles, the combinationwith a series of upper rolls adjustable horizontally in a line at anangle to their axes, of a series of rolls horizontally, and horizontalladjustable means for driving the lower ro ls.

l. In an apparatus for straightening metallic articles the combinationwith a series of lower rolls, of a series of upper rolls, means foradjusting the rolls of the upper series vertically, independent meansfor adjusting the rolls of the upper series horizontally in a line at anangle to their axes, and means for adjusting the rolls of the lowerseries horizontally.

5. In an apparatus for straightenin metallic articles, the combinationwith a ame and a series of rolls mounted therein, of a series ofhousings mounted on the frame, means for adjusting said housingslongitudinally of the frame, rolls mounted in said housings, and meansfor adjusting said last mentioned rolls in lines at righbangles to thatof the adjustment of the housings.

6. In an apparatus for straightening metallic articles, the combinationwith a pair of rolls having their axes in parallel rotation, of a thirdroll having its axis parallel to those at the otlfer rolls and arrangedbetween but out of line with said pair of rolls, means for adjustingsaid third roll in a line at right-angles to the common lane of the axesof said pair of rolls, and in epen'dent means for adjusting said roll ina line parallel with said common plane.

'7. In an apparatus for straightening metallic articles, the combinationwith two series of rolls mounted on two series of roll-shafts ha ringtheir axes arranged in parallel planes, of means for adjusting the rollsof one series in the line of its plane, means for adjusting the rolls ofone series at right angles thereto, and me: us for driving the rolls ofone series.

8. In a machine for straightening metallic articles, the combinationwitlrtwo series of rolls having their axes arranged in parallel planes,of means for adjusting each roll independently of the others in the lineofthe plane of its series and in a line at right angles thereto, andmeans for driving the rolls of one series.

In testimony whereof I have hereunto se my hand.
